The customer is always right, right? Unless it comes to putting ketchup on a Philly cheesesteak outside of Philly.

A fight broke out, 911 was dialed and a Subway employee was fired all because a guy wanted ketchup on his cheesesteak, according to reports by NBCPhiladelphia, and Yahoo News.

Customer Luis Martinez said he went into the Subway shop and ordered a Philly cheesesteak at the Florida franchise, specifically requesting "American cheese, onions and ketchup."

Cheese? That's fine. Onions? They had them too. But ketchup was unheard of. Subway didn't have any of the condiment Martinez was craving.

"He wants ketchup on the Philly cheese steak and I have never put — we don't even have ketchup at Subway — I've never put ketchup on anybody's sandwich," Ordone was reported saying.

Angry words were exchanged. Chairs were thrown. Tables were tossed.

"He shoved a chair to the side, like knocked it down to come at me, and I said, 'This is going to be serious,'" said Martinez, according to Gawker.

"There's ketchup three aisles down. You can go buy your own ketchup, and I promise to God, you can put as much as you want on it and nobody's going to say nothing," said Ordone said according to Gawker.

Martinez said that Ordone then threatened to kill him, which Ordone denies.

According to Yahoo News, Martinez called 911 and by the time police arrived the employee had already left. Ordone was later fired from Subway. There were no physical injuries and no arrests were made but police may refer the case to the State Attorney’s Office to determine if Ordone will be prosecuted.
